LG 50PS3000 picture problems


Standard Member
Hi Guys i am looking for some help.

I have recently aquired a LG plasma TV as the picture quality went on it.

I get a red grainy picture.

I have changed the Ysus board, the 2 Ysus buffer boards, the Zsus board and the PSU board, and finally the Control board.

None of the changes above have made any difference.

So far spent in the region of £230 changing the fore mentioned boards.

Any ideas. I do have pictures of the picture quality of the TV.

If you know were I can get a circuit diagram for this TV much apreciated and also would changing the main AV input board make any difference.

Please Help Guys

You'd do far better posting on a dedicated TV repair forum.

Although there are a few who post on here who have some experience of electronics, the chances of anyone (other than an LG dealer or TV repair shop) having access to the information you require is extremely remote.

Won't the suppliers of the replacement parts you've bought offer any guidance ?
